Stage 3: Design development

After design and Budget approval, we can assemble the team of professions - QS and Engineers

The design development stage will commence once the final concept design, along with estimated budgets, are approved.

The plans will then be further developed based on the approved concept design, with any further changes that may be required, as well as the input from the consultants. In the case of the input from the structural engineer, this will include the specifications of the foundations, suspended floors and the roof design. At this stage details, specifications and any adjustments required in terms of energy efficiency will also be undertaken. The design development will include details of the construction systems and materials to be used.

After any further changes are made, the final set of design development plans are produced. These will include detailed floor plans, sections showing the materials and structural systems being utilised, as well as detailed elevations. The design, costing and programme will then be reviewed with the consultants. The building cost and fee estimate will be adjusted to suit the revised design and areas, by the architect, or by the quantity surveyor if one has been appointed.
